Whether the one-year period for patent application starts from the time of application or from the date of authorization announcement, I hope professionals can give me some advice, thank you.

Patent applications are protected for 10 or 20 years, calculated from the date of application. stipulated in the patent law. Patent protection fees are calculated and paid based on the filing date. However, payment will start from the year of authorization and will not be paid before authorization. For example, if the authorization is granted in the third year, there is no need to pay annual fees for the first and second years. The initiation of proceedings must follow authorization.
